FEED FOR COTTON-GINS.

SPECIFICATION forming part of Letters Patent No. 657,084, dated September 4, 1900.

Application filed February 23, 1899. Serial No. 706,606. (No model.)

To to whom it may concern.-

Be it known that I, JAMES E. OHEESMAN, of the city, county, and State of New York, have invented a new and useful Feed for Cotton- Gins, of which the following, taken with the accompanying drawings, on two sheets, is a description.

The object of my invention is to provide a device which will feed the seed-cotton to the machine without a special operator therefor, Without jamming-it up against the roller, and in quantity adjusted to the capacity of the roller.

It consists, substantially, of a series of upright fingers or pins entering the mass of seedcotton through the bottom of a hopper and carrying forward successive portions thereof to the ginning-roller.

In the annexed drawings,in which the same letters indicate corresponding parts, Figure 1 is a sectional side View, and Fig. 5 a side elevation, of a cotton-gin (in this case a rollergin) fitted with my present invention. Figs. 2, 3, and 4 are sectional side views of the main parts thereof, showing three positions of the cotton-feeding device. Fig. 6 is afront view showing the relation of the moving fingers to a set of stationary pins at the rear of the hopper. Figs. '7 and 8 show certain adjustments.

A is the frame of the machine.

B is the ginning-roller, O the fixed guard, with its edge in contact with the ginningroller, and D the stripper operating up and down to strip the seed-cotton of its seeds as the roller B by its revolution draws the fiber down between itself and the guard O.

E is a hopper stretching across the front of the machine and having its back board F and its front board G approaching each other somewhat in V shape, so as to allow the mass of seed-cotton to drop by gravity to the point nearest the roller. The back board F has as its bottom edge a series of downwardly-projecting fingers or pins c, Fig. 6, and the front board G has a series of fingers or pins 0 projecting toward the ginning-roller or somewhat downward. When the machine is at rest, the mass of seed-cotton is held in the hopper E, with its lowest portion resting against the pins 6 and the pins 0, the ends of which approach each other sufliciently to confine it, but without touching each other.

The moving part of the device consists of a series of upwardly-projecting pins 0,, fastened upon a board or rod H, Fig. 6. At each end of the machine this board H is attached to an eccentric J, with its eccentric-rod n. A small stationary roller 1) forms a bearing-surface for the eccentric-rods 'n, and springs 1) keep the eccentric-rod continually against such roller.

In Fig. 5, K is the pulley driving the stripper D. R is the pulley driving the ginningroller B. Attached to the ginning-roller B is a sprocket wheel L, connecting with the sprocket-wheel M on the shaft of the eccentric J through the chain P. The ginningroller B thus drives the eccentrics J and the feeding device. The relative number of teeth on the two sprockets L and M can be varied to determine the relative speed of the ginning-roller and the feeding device.

The operation is as follows: The mass of seed-cotton is thrown into the hopper E without any special care. The eccentrics J cause the pins 0. to pass up into the seed-cotton,

grasp and carry forward a small portion of the same between the successive pins e, deliver it to the ginning-roller B, and thereupon withdraw. These successive positions are shown in Figs. 2, 3, and 4. The pins a are so arranged with reference to the pins 0 and e as to pass between them. The portion of cotton grasped and carried forward by the fingers a is passed between the pins 6, and this operation has the effect of straightening out the fibers and loosening the bolls. The dropping down of the pins 0 after they have passed the pins 6 causes the cotton to be fed to the ginning-roller in a loose condition instead of being jammed up against it tightly, as is done with the ordinary feeding device, and allows the stripper to do its work with out hindrance by the jamming of the cotton, while on the other hand the cotton can be fed as fast as the roller is capable of taking it by simply speeding the eccentrics J. No operator is necessary, as with the ordinary feeding device, since this feeding device is wholly Ice automatic and the cotton requires no spreading out or loosening before being grasped by the pins a. The pins Ct do all that Work.

Fig. 7 shows an up-and-down adjustment of the pins 6, so that the pins a and the pins 6 may be made to overlap to any required extent. Abolt cl is attached to the back board F of the hopper and passes through slots 9 in the sides of the hopper, a set-nutf engagingwith such bolt to fasten the back board F in any desired position.

The piece H, carrying the pins Ct, can also be adjusted back and forth-that is, toward or away from the ginning-rol1er--by means of the eccentric-rod n, having right and left threads on its two ends, engaging with corresponding threads upon the board H and the shank m of the eccentric J. (See Fig. 8.)

I claim as my invention 1. A feed for cotton-gins consisting of the combination of a hopper'having an opening at the bottom and also having a back board with a downwardly-projecting series of fingers and a piece carrying an upwardly-proj ectin g series of fingers actuated by an eccentric, and causing the second series of fingers to grasp the cotton and carry it between the fingers of the first series.

2. A feed for cotton-gins consisting of the combination of a hopper having a back board with a series of downwardly-projecting fingers, a piece carrying an upwardly-proj ectin g series of fingers and actuated by an eccentric;

the back board of the hopper being movable up and down so as to raise or lower its series of fingers.

3. A feed for cotton-gins consisting of the combination of a hopper having as its floor a series of fingers projecting toward the gin, having also a back board with a downwardlyprojecting series of fingers With a piece carrying an upwardly-projecting series of fingers, actuated by an eccentric, to cause the last-mentioned series of fingers to pass between the fingers and the other two series.

In Witness whereof I have hereunto subscribed my name', in the presence of two witnesses, this 31st day of January, 1899.
